Lowering on land surface which is commonly known as land subsidence is quite an issue in Indonesia today especially for coastal low elevation young sediment area, including cities or urban area lies on top of it. Jakarta is one of the city with most famous for land subsidence at the moment. If we go along northern coast of Java, many cities are experiencing the same situation as Jakarta and even more. As the impact from land subsidence, those coastal areas may experience water disaster such as sea water inundation and intrusion, wider expansion of flood and aquifer damage. Investigation of such areas in large and even regional scale with limited research budget is a problem. Nevertheless we found way for at least reducing the problem by using the capabilities of remote sensing product, geological and geostatistic data. We can identify land subsidence, coastal effected by subsidence like mentioned above by only time series of satellite image archive such as Google earth or Landsat free distributed, geological map and published geostatistic data like water consumption and population growth, with sample validated by land subsidence measurement and groundwater monitoring points. This paper will highlight our finding.
